He was sinking. Every second he was heading deeper and deeper into the dark abyss beneath him. He was descending into an ocean of pitch black, the weight of which was too heavy to fight against. He couldn't swim back up, he could barely even move a muscle. All he could do was keep sinking further and further into darkness.

Suddenly he his body seemed to turn upright. He floated down slowly, and felt his foot land on something flat. The moment his foot touched the flat surface, it began to light up. The light spread across the surface as he managed to get both feet firmly on the ground. He steadied himself and then looked around. He could actually see what he was standing on. It was some kind of… circular platform.

There was a design on it. It looked like… some type of wheel. It had a large triangular being with a top hat and one eye in the middle of it, while the outside of had… some type of symbols. There was a tree, a bag of ice, a questions mark. None of it really made any sense to him. Was this some kind of puzzle?

So much to do, so little time... Take your time. Don't be afraid. The door is still shut. Now, step forward. Can you do it?

He looked around nervous, wondering where the voice had come from. All he saw around him through was darkness. Well, standing here wasn't going to get him anywhere. He stepped forward. All of a sudden, the ground shook. He looked around wearily as three stones rose from the ground. Each of them presenting an item on top.

One was a sword. The other a shield. The last was a staff.

If you give it form... It will give you strength.

Choose well.

He looked around at the three items confused. This was all happening so fast. He didn't know where he was, or how he even got here. Now he was supposed to be picking weapons. None of this made any sense. He sighed. Whether it made sense or not, nothing was going to change if he just sat in.

He walked towards the sword. The power of the warrior. Invincible courage. He smiled and reached out to grab it. A sword of terrible destruction. His hand stopped. Terrible destruction? That… that didn't sound good at all. Is this the power you seek?

He shook his head and backed away. Invincible courage sounded great, but the last line kept hanging on his mind. He moved towards the shield. The power of the guardian. Kindness to aid friends. A shield to repel all. Is this the power you seek?

He thought for a moment. This one didn't seem anywhere close to as bad as the last option. But for some reason, he didn't see himself as much of a guardian. And the 'repel all' bit… that didn't sit to kindly with him either. What about what he didn't want to repel. It was too ominous.

Deciding not to dismiss the shield just yet, he checked out his final option. The staff. Inner strength. A staff of wonder and ruin. Is this the power you seek? He looked closely at the staff. It didn't seem like much compared to the other weapons. But what he'd heard. Wonder and ruin. That ruin line was definitely fishy, but then against so were the other option.

And wonder… he always was curious. If there was new wonders to be found, then he was all in. He reached forward and grabbed the staff. Your path is set. The staff suddenly vanished from his hand, causing him to jump. Now, what will you give up in exchange?

He took his the two remaining options. Honestly, it wasn't that hard for him to decide. Just looking at the sword reminded him of 'Terrible destruction'. The power of the warrior. Invincible courage. A sword of terrible destruction. You give up this power?

He nodded. You've chosen the power of the mystic. You've given up the power of the warrior. Is this the form you choose? Once again, he nodded.

The stones suddenly vanished, and he found himself falling once more. This time his descent was much shorter. When he landed and the next platform lit up, a picture of a hand with six fingers on it. It was one of the symbols from the earlier platform. Only this time where were numbers surrounding it. The numbers 1, 2, and 3, surrounding it in a triangular pattern.

The staff reappeared in his hand. You gained the power to fight. He looked at the staff hesitantly, then gave it a good swing. It felt light, but… sturdy. Hmm.

All right! You've got it. Use this power to protect yourself and others. Suddenly, shadows appeared. He looked at the group in shock. They were like pitch black cockroaches. With creepily yellow eyes. There will be times you have to fight. Keep your light burning strong.

They leapt at him, and he quickly jumped back. He didn't know what these things were, but clearly they weren't friendly. The voice was right, he had to fight. But would this staff really do anything to them? He gripped it tightly. Time to find out.

He charged forward and swung, nailing one right in its head. He gave another swing, and another, not giving it time to attack back. It fell to the ground and dispersed, and the others charged in. He quickly turned the weapon on them next. It was strange. He had fought before, but he'd never been very good at it.

Between him and his sister, she was the more physical of the two. But the weapon felt so… natural in his hands. Like he'd been using it for years. He stuck them a few more times. Then, they disappeared. More appeared.

Behind you!

He turned around and knocked away one that had tried to blind side him. He made a mental note to thank… whoever this voice was. For now, though, he needed to keep fighting. After about a minute of the black creatures assaults, they finally seemed to stop coming.

A pair of stairs appeared. Seeing no other option, he began making his way down to yet another platform. This one was just a star with a multitude of color surrounding it. It almost reminded him of his sister favorite sweater. He spotted a pair of doors, and made his way towards them. He pushed them open, and a bright light blinded him as he walked though.

He then found himself in a familiar place. The Island. His home. Hold on. The door won't open just yet. First, tell me more about yourself. What are you afraid of?

He looked down in thought. "Being out of the loop. Being… lost, helpless…"

Being lost? Is that really so scary?

"It is to me." He said sternly.

What do you want outta life?

He smiled. "To see rare sights. To go on adventures, solve mysteries. Learn about the world. All of them." He said proudly.

To see rare sights, huh? What's most important to you?

He didn't even have to think on that one. "My sister."

Is she really so important to you?

"More important than anything." He said firmly.

You're afraid of being lost. You want to see rare sights. You treasure you sister. Your adventure begins at dawn. As long as the sun is shining, your journey should be a pleasant one.

"Sounds good."

The day you will open the door is both far off and very near.

The scenery around him changed, and Dipper found himself on another platform. This time there was a picture of… his sister. "Mabel…" Before he could even start pondering what this meant, another group of Shadows appears. He sighed. "Getting really tired of you guys…"

He lifted his staff once more and charged. He made quick work of them all, and afterwards another pair of staris revealed themselves to the next area. He reached the bottom.

The closer you get to light, the greater your shadow becomes.

He gasped as his own shadow suddenly began to rise from the ground. It morphed into a large shadow creature, one that dwarfed the other in size. It towered over him, glaring down with those burning yellow eyes.

But don't be afraid. And don't forget...

He backed away, until he almost fell off the edge of the platform. He turned back to the creature which began making its way towards him. Looking around desperately, he could see there were no other exits. He didn't have the option of fight or flight. It was just fight apparently.

"AAAHHHH!"

He gripped the staff and charged at the being. It swung it arm down, but he rolled out of the way and struck its hand. The beast didn't show much reaction, but the hand looked like it had taken some damage at least, so he kept at it. He kept swinging and swinging, dodging it's attack and striking blow after blow.

So long as he stayed quick on his feet, this thing would never be able to catch him. It punched down at him, and he jumped straight up as its fist crashed into the floor. He landed on the back of its hand, before quickly running up its arm. This was his chance.

He swing the staff, striking it in where he assumed its temple would be. It let out a roar before falling back. He jumped back onto the ground as the creature hit the floor. He smirked. He'd somehow managed to win. It was a miracle.

Suddenly, black circles formed below him. He panicked as they quickly began to engulf him.

But don't be afraid. You hold the mightiest weapon of all.

He struggled as he sunk lower and lower into the black circle. Was this it? Had this voice led him all the way here so he could drown in darkness?

So don't forget: You are the one who will open the door.

Everything turned pitch black.


Dipper Pines' eyes shot open and he quickly sat up. He breathed in and out, trying to steady his breath. What… what kind of dream was that? It was so weird. Monsters, doors, mysterious voices asking personal questions. Was his psyche trying to tell him something, or had that pizza he'd eaten last night just bad.

"Wow, someone looks like they had a nice little nap." Dipper looked over and saw his sister siting on a nearby rock. "Welcome back to the world of the living lazy bones."

He groaned and rubbed his head. "Don't bug me now Mabel. I just had a dream that… I don't know what it felt real." He said shaking his head. "There were these living shadows, and doors, and this voice kept on asking me questions…"

Mabel tilted her head. "Hmm? Sounds more like you stayed up late watching monster movies again. Or did the pizza you eat go bad?" She asked giggling.

Dipper scowled at her. "Very funny Mabel."

"I know." She said shrugging her shoulders. "But enough about your weirdo dream little bro, we need to get working on the raft. I spent all day gathering up supplies, and you spent all day… napping apparently." She said pouting at him.

He scoffed. "I worked on the raft some. All I have to do is finish securing the mass, and this baby will be ready to sail." He said looking at his work. His annoyance disappeared at the very sight of the boat. "We'll finally be able to travel to other worlds. To see what else is out there. Think of it Mabel. New people, new places, new wonders."

She nodded. "Yeah… maybe I'll find a cute boy to marry out there!"

Dipper rolled his eyes. "Figures. We're going to explore new worlds and all you can think about is finding a boyfriend." He said chuckling. "Anyway, I'll get finish up with this and we can head back to dinner… you know if mom and dad are back yet?"

Mabel frowned. "No. Haven't seen them all morning."

Dipper sighed. Their parents were hardly ever home. He knew they had their jobs. That they were busy trying to support this little family. But even when they were home, they barely noticed the twins. It was almost as if they had no parents at all really. "Should we… should we really leave without telling them?" She asked.

"Mabel, they'll try and stop us." Dipper said bluntly. "I love them, they're our parents, but I can't just sit here and waste away the rest of my life on this island for them. There are other worlds out there to be explored, and I plan on seeing them. We'll leave them a goodbye note or something."

The female twin looked down conflicted, but then nodded. "You're right. I feel bad about leaving them, but we can't stay here." She then gave her brother a light punch on the arm. "Besides, I'll have you there the whole time. We're all the family we need, right?"

Dipper nodded. "Right."

Mabel turned back to the rest of the supplies she had gathered, and then snapped her fingers. "Oh yeah, I almost forgot!" She pulled up a strange looking fruit.

"Paopu fruit…" Dipper said amazed. They were super rare on the island.

His sister nodded. "Found it over near the waterfall, and I just couldn't pass up this chance." She said before tearing the fruit in two. She held one out to her brother. "You know what they say right? If two people share one, their destinies become intertwined. They'll remain a part of each other's lives no matter what."

Dipper smiled. "Mabel, we're twins. Being forever part of each other's lives is kind of a given, don't you think?" He asked.

"I know. But a little extra insurance never hurt anyone right?" She asked. Dipper chuckled before taking the other half of the fruit. "Enjoy!" With that, they both took a bite of the fruit, and their faces lit up. "So good…"


The raft had been completed, and the twins had gone to bed. Once again, their parents were nowhere to be seen. They'd decided to head straight to bed. They would need to be rested and ready to set sail tomorrow. Dipper was thankful he hadn't seen anymore weird dreams. But there was something else that ended up disturbing his slumber.

The flash of lightening followed by booming thunder jolted Dipper awake. He groaned and ran his hand over his face. "Jeez, can't a guy get any sleep around here. Weird dreams, loud storms… wait, storm?!" He shot up out of his bed and looked out of his window. Yep, it was definitely storming right now.

He looked up at the dark cloud, and then down at the raging water. "The raft…" He muttered. He quickly turned around and sped towards the door. He needed to save the raft! He'd put so much time and effort into it! It was their only escape! Why did it have to storm now of all times?! He thought about waking Mabel, but decided not to. He could do this on his own. She needed her rest.

As he made his way to the docks, he saw a figure already standing there. He stopped. "Hey! Who are you?" He asked. What were they doing out here in the middle of their storm, and why were they standing near the raft?

The figure turned around. It was a boy, he looked fifteen or so, with jet black hair. He was wearing jeans, and a black hoody with a stitched up heart on the front of it. He smirked at him. "The door has opened."

"What?" Dipper asked confused.

"The door is open squirt. You and your sister. You can travel to other worlds now." He said raising his hands.

Dipper flinched. "What… what do you know about me and my sister?!"

"Don't worry kid. You don't need to panic. She's coming with us." He said laughing. Dipper glared at him. "Just know kid, once you step through the door, there may not be any turning back. Your family and friends, everyone you left here, you could never see them again. But you going to let fear stop you?"

Dipper kept glaring at him. He didn't know who this guy was, but he felt a chill up his spine whenever he talked. Shadows suddenly appeared around the both of them, engulfing them. Dipper panicked, and quickly began trying to pull himself out. The boy just smirked.

Suddenly a flash of light went off, and the shadows around Dipper vanished. The teen merely shook his head and chuckled. "Hmm, your call. Good luck." With that, the boy turned around, and the shadows rose up, engulfing him before sinking into the ground and disappearing.

Dipper stood there stunned, but then looked down at his hand. He was now holding some kind of weapon. It looked like a sword, but it was oddly shaped. Kind of like a key. The teeth of the key was shaped like a book, with the number three engraved on the side of it. It had little key chain with a pine tree at the end of it.

Keyblade… Keyblade…

Dipper's eyes shot up. There was that voice again. This was just like his dream. Only this time he was one hundred percent sure he was awake. Were more of those monsters going to show up again? Was that giant shadow going to… "Mabel!" He had to find her! To make sure she was okay! He rushed back towards the house, only for more shadows to appear in front of him.

He growled. He didn't have time for this! He needed to make sure Mabel was okay. "Move!" He shouted angrily as he swung the key. It cut through the shadow creatures like a hot knife through butter. He kept running, cutting down any shadow that dared stand in between him and his sister. "Mabel! Mabel!"

Halfway towards the house, he heard a scream. "MABEL!" He quickly turned towards the source of the cry. The waterfall. He rushed to the cave behind said waterfall, still cutting his way through the shadows. When he reached the end, he saw Mabel standing in front of some door. She looked like she was sick. "Mabel! Mabel, are you okay?!"

"Dipper…"

The door behind her suddenly opened, and a black wind shot out from it. It sent Mabel flying towards him. She quickly reached out to grab her, but was stunned when she went flying right through him. He gasped and turned around. "MABEL!" Another gust of wind came by and he was sent flying by it as well.

Dipper's vision was a blur. He couldn't make out where he was going. He suddenly landed on a flat surface. With a groan, Dipper pushed himself up to his feet. He looked around and saw he was on one of the platforms from his dream earlier. "What the…?" A noise caught his attention, and he looked up to see the shadow monster from earlier before him.

He narrowed his eyes. "Where's my sister?!" He demanded. The monster gave no reply. It only raised its hand an prepared to strike. He lifted the key. "I'll beat it out of you if I have too!" He shouted angrily. Again, no reply. It swung down on him.

"AAAHHHH!"

He ran forward and side stepped the monsters attack while swinging the key. It slashed against its wrist, and the monster recoiled. Dipper rushed beneath its legs and then slashed as its ankles. It stumbled forward, and he quickly ran up its back. "Give me back my sister!" He yelled jumping upwards. He brought the key down on the back of the monsters neck.

It roared out in pain before suddenly dispersing into the ground. Dipper landed on the ground and turned towards the darkness. He balled his fist up. Killing that thing hadn't gotten him any closer to Mabel. A black sphere suddenly appeared and began pulling everything inside. "Oh come on!" Dipper shouted trying to run.

He struggled to escape its pull, but it was futile. He was quickly pulled inside of the sphere, and once again his vision turned black.


Dipper slowly opened his eyes to the sight of a… a pig. "What?" He said tilting his head to the side. "Another dream? I've gone from giant monsters to pigs huh?" As if insulted by being thought of as a dream, the pig placed it front legs on Dipper's chest and pressed his snout against his cheek. "AH! It's not a dream!"

The pig backed off, allowing him to get to his feet and dust himself off. He looked around and saw that he was in some alley way. "This… isn't the island. Where is this?" He asked looking around. He turned to the pig. "Do you know where I am?" He knew he shouldn't have expected an answer, but after everything that just happened, talking pigs wouldn't surprise him.

The pig grunted before turning and running away. Dipper scowled. "Stupid pig…" He began making his way out of the alley. He looked around and realized this was some type of town. He thought of what his next move should be. He probably should have asked someone where he was, but he didn't see anyone. And all of the stores around seemed closed.

"Where am I supposed to…" The solution to his problem came in the form of a nearby Diner. The sign had read closed, but he could see the lights were on. And there were figures inside. "Well, got to start somewhere." He said making his way towards the place.


A/N: Could not get this idea out of my head. It just kept on bugging me and bugging me. I'm sure I'm not the first person to think of a Gravity Falls/Kingdom Hearts AU, but I'm going to take a shot at it anyway.

This first chapter was modeled after the first scenes of Kingdom Hearts obviously. Some of the dialogue was changed around to fit Dipper and Mabel's character. As the story goes both the scenes and dialogue will change from the original script from the game. Rather than Disney Worlds, they'll be visiting worlds of other cartoon.

Steven Universe, Danny Phantom, SVTFOE. They'll all be making appearances.

As you can guess, Dipper is the main character here. Mabel will play a roll similar to Kairi, and Robbie similar to Riku. Of course neither of the twins know Robbie by this point. The rest of the cast from Gravity Falls will be making an appearance next chapter. Hope you guys enjoyed it! Remember to review and tell me what you think!
